1.6MHz Boost Converter

with 30V Internal FET Switch

General Description

The TS1935 switching regulator is current –mode boost

converters operating at fixed frequency of 1.6MHz.

The use of SOT-25 made possible by the minimal power

loss of the internal 1.6A switch, and use of small inductor

and capacitors result in the industry’s highest power

density. The 30V internal switch makes these solutions

perfect for boosting to voltages up to 30V.

These parts have a logic-level shutdown pin that can be

used to reduce quiescent current and extend battery life.

Protection is provided through cycle-by-cycle current

limiting and thermal shutdown. Internal compensation

simplifies and reduces component count.
